I am a beautiful gazelle, crouching in the froggy marshes of a pond.
As I jump, my winds fly out from my sides, pushing me into the air.
But just as I reach a height I am pulled back, my neck enclosed in a studded leash.
I see a ball thrown in the air, and I start to gallop across the free-born plains,
My tentacles moving over the earth as I plunge in the water,
My tail flipping past the waves.
I swim callously to the surface, my legs kicking, my arms pushing.
At the edge of sand I walk, smoothly, into the waiting family of my kin.
What am I?
